1,3-Butadiene → HCID 86584203, compound

Participants

Reaction Conditions

Reaction Steps

The temperature of the autoclave was raised to 40° C. and thereafter 667 g of a cyclohexane solution of 30% by weight of butadiene (Bd) (Bd: 200 g) was introduced into the autoclave to carry out a polymerization reaction at 40° C. for 2 hours, obtaining a Bd homopolymer. Then, 200 g of 1,3-cyclohexadiene (CHD) was further introduced into the autoclave to carry out a polymerization reaction at 40° C. for 5 hours. After the polymerization reaction was completed, dehydrated n-heptanol was added in an amount equimolar to Li atoms to terminate the polymerization reaction. Desolvation was effected by a conventional method to obtain a Bd-CHD di-block copolymer.
